Phytochemical study on the Philippine endemic Annonaceae plant Uvaria valderramensis afforded a new highly oxygenated seco-cydohexene derivative, valderepoxide (1), along with the six known compounds uvamalols D (2) and G (3), grandiuvarone (4), 2'-hydroxy3',4',6'-trimethoxychalcone (5), valderramenol B (6) and benzoic acid. The structure of 1 was determined through extensive spectroscopic analyses including 1D, 2D NMR and HRESIMS. Its relative stereochemistry was established using 2D-NOESY. This is the first report on the isolation of polyoxygenated compounds 1-3 and chalcone 5 from U. valderramensis. (C) 2017 Elsevier Ltd. All rights reserved.
